On pump gas you won't be able to run nearly this aggressive. Perhaps in the 320-330whp range. Next time around they will do some back to back dynos on the JB4 G5 ISO on 93 octane vs. the Cobb Aggressive map same car, same day, same dyno.
In terms of race maps it looks like E40 is enough to basically completely max the turbo out with this timing curve. There may be another couple of HP in there with more advance via a BMS back end flash but I'm not expecting much. We've definitely found the limits of the N55 stock turbo. Right around 400rw all in FBO.
